What is the Scientific Method?• It refers to the steps someone takes to…

1) Identify a question

2) Develop a hypothesis (educated guess)

3) Design an experiment

4) Record observations

5) Make a conclusion

In other words.. it’s a way to solve a problem!

Scientists think carefully and

logically when they…

(1) investigate a question or

problem.Ex: What is in this box?

Scientists develop a question, gather information and… (2) form a hypothesis-- an educated guess.

Ex: If the object inside the box is bouncy and rolls around, then it is a superball.

Writing a Scientific Hypothesis:

If…, Then…Ex: If the check is for Auto Body Shop, then she went to go fix her car.

The next step scientists take is to… (3) create and conduct an experiment to test their hypothesis.

Ex: Move the box side to side to see if the object is rolling or sliding.

A key to experiments is… (4) observing what happens and writing it down.

Ex:

Box# Observations Object

(4a) QuaLitative Observations are based on Looks!

Note: There are 2 types of observations!

Color, shape, size, texture can be used to make observations.

Ex: The ball is small and rubbery.

(4b) QuaNtitative Observations are based on Numbers!

Make these observations by counting or measuring with a tool (ruler, scale, etc.).

Ex: The metal pipe weighs 5 grams.Ex: There are 12 checks.

Make 1 quaLitative observation and 1

quaNtitative observation:

Note: Gathering information or data and recording it so it is readable and makes sense to others is really important.

Don’t be a mad scientist!!

Once a scientist completes an experiment, they will… (5) repeat the experiment to see if they get the same results.

This is called verification-- checking things out to make sure everything was correct

and the results will be the same over and over.

Scientists also need to… (6) share their experiments and conclusions with others.

Because they share their experiments and findings, scientists can learn from each other and often use someone else’s experiences to help them with what they are studying or doing.

The steps of the Scientific Method are:

• Question

• Background Research

• Hypothesis

• Procedure (Experiment)

• Data (Observations)

• Conclusion

Make 1 quaLitative observation and 1

quaNtitative observation:

Graphing Preassessment!

Directions: Create a line graph based on the below data. Include all elements of a proper graph. You will be given 5 minutes.

Experimental And Control GroupsExperimental And Control Groups

In order to test something, we must have a comparison.

- Experimental group: one being tested

- Control group: comparison to the experimental group

In an experimental and control group, only the independent variable is changed.

Medicine example - clinical trials (placebo)

Warm Up – September 3, 2015

Objective Copy the following:I can identify in writing the independent/dependent

variables & control/experimental groups of an experiment.

Do Now Answer: 1) List the steps of the scientific method (complete sentences not necessary).

2) Choose one step and circle it. 3) Explain, using complete sentences, what that step

contributes to the experimental process.
